Silicon Heater hose 3/4"

Designed for low pressure water and normal heater applications, G382 Silicone Heater meets or exceeds SAE20R3 Class A specifications.

Material:

Silicone is one of the most stable rubbers. It remains flexible and resists aging after prolonged exposure to extreme temperatures, weather, ozone, and oil. This long-lasting property yields hoses that operate reliably in environments which destroy most other rubbers. Because silicone does not harden and crack with age, silicone radiator hose will give a service life of one-half million miles or more on highway trucks and buses - much longer than standard coolant hoses.

Clamps:

Wire clamps are not suitable for silicone hoses. For heater hose and small sizes of coolant hose, we recommend extended tang worm-gear clamps (part number G7ET). Extended tang clamps are designed to prevent damage to the outside cover of the hose normally caused by serrations on standard gear clamps. Recommended torque is 30 to 40 inch pounds. G5A non-perforated Type 316 Stainless Steel clamps are popular for silicone hose in marine applications for added corrosion resistance. For larger sizes, we recommend G39 spring-loaded T-Bolt clamps to maintain even clamping pressure. Always recheck clamps shortly after installation to ensure proper installation (when engine is cold).
